Remeber this is in an equal one on one fight, of course lions have taken down these animals in packs or have killed their sick, old and young. I'm talking about a fully grown healthy lion against a fully grown healthy opponent. Encounters are rear so the first catergory is partly speculation the second category is based on fact (Bears and Tigers fought lions in ancient rome and almost always won) and It's obvious that the big five herbivores are far too big for a lone lion. If there is any other land animal that has a chance against a lion please say.
Large Brown bears have been known to kill lions with one strike to the head.
